Barrier Option
A barrier option is an option whose payoff or existence depends on whether the underlying asset reaches a specified barrier level.
Barrier, knock-in, and knock-out option terms used when payoff activation depends on a price trigger.
Barrier, Knock-In, and Knock-Out Options is the financial-instruments landing page for Asian options, barrier options, knock-in options, knock-out options, digital options, lookback options, path-dependent options, and quantity-adjusting structures. It keeps related terms in one branch so readers can move from a broad instrument question to the article that owns the contract evidence.
Use this page when a nonstandard option feature changes activation, observation, payoff path, or settlement value. Use the parent Exotic, Path-Dependent, and Barrier Options page when you need the broader instrument map. For an individual decision, confirm the contract, term sheet, prospectus, confirmation, exchange specification, or disclosure record before relying on the term.
